Begin by dicing the Yukon Gold potatoes into small chunks so they cook evenly. Finely chop the onion and mince the garlic cloves.
Place the boneless, skinless chicken breasts at the bottom of the slow cooker.
Add your diced potatoes, chopped onion, and sweet corn on top of the chicken.
Pour in four cups of low-sodium chicken broth until all ingredients are fully submerged.
Pour in one cup of heavy cream or whole milk and season with salt and pepper.
Cover your crockpot and set it to cook on low for 6-8 hours or high for 3-4 hours.
Remove the chicken breasts from the pot and shred them using two forks. Stir everything together well.
